Role Description:

Role Overview

As a Full Stack Software Engineer II, you will work end‑to‑end across front‑end and back‑end systems to ship features that directly impact our customers and partners.

• Design, build, and operate end‑to‑end product features across the stack (front‑end, back‑end, data & integration).
• Work in a cross‑functional team (product, design, data, other engineers) to solve real customer problems.
• Take ownership from design and implementation to production, monitoring and iteration.
• Contribute to engineering quality, reliability, and best practices within your team.
• Rapidly develop next‑generation scalable, flexible, and high‑performance services for the SS&F Department.
• Design, develop and maintain high critical services serving production workloads.

Key Responsibilities

• Design & build end‑to‑end features across web front‑ends and back‑end services.
• Implement and evolve APIs and microservices (REST/GraphQL/event‑driven) that are secure, scalable, and observable.
• Develop user interfaces using modern JavaScript/TypeScript, HTML/CSS and a component‑based framework (e.g. React or equivalent).
• Strong experience designing and implementing backend services in Java (or similar JVM languages), including APIs, business logic and integrations.
• Work with relational databases (e.g. MySQL) and caching solutions to model, store and retrieve data efficiently.
• Write high‑quality, testable code with unit, integration and end‑to‑end tests as appropriate.
• Use CI/CD pipelines to ship changes frequently and safely.
• Monitor services in production (logs, metrics, traces, alerts) and participate in on‑call / incident response where applicable.
• Collaborate closely with product, design and data to refine problems, define solutions and run experiments (A/B tests).
• Contribute to technical design discussions, code reviews, and knowledge sharing.
• Champion security, privacy, performance and reliability in your solutions.
• Mentor junior engineers informally and help raise the engineering bar in the team.

Required Qualifications

• 5–8 years of professional software engineering experience, including production systems.
• Have a strong drive to build high quality systems and improve the quality of existing systems.
• Strong skills in back‑end language (Java, Spring Boot / Dropwizard) and one modern front‑end framework (e.g. React).
• Experience building and consuming HTTP APIs / microservices.
• Solid understanding of data structures, algorithms, and object‑oriented design.
• Hands‑on experience with relational databases (MySQL or equivalent) and writing efficient SQL.
• Experience with automated testing (unit, integration; familiarity with test pyramids and quality gates).
• Experience using CI/CD tools and version control (Git).
• Comfort working in agile, cross‑functional teams and collaborating with non‑engineering stakeholders.
• Strong communication skills, with the ability to explain trade‑offs and make pragmatic decisions.
• Mindset of ownership, learning and continuous improvement.
• Experience using modern AI tooling (e.g. Claude, GitHub Copilot, Windsurf or similar) to accelerate design, coding, testing and documentation, while maintaining high engineering standards.
• Experience operating high‑volume, low‑latency services in production, including performance tuning, capacity planning and incident handling.
• Hands‑on experience with AWS cloud services (e.g. EC2/EKS, S3, RDS, networking and monitoring) for deploying and operating backend workloads.

Nice‑to‑Have

• Experience with high‑traffic, distributed systems and performance tuning.
• Exposure to Kubernetes / container orchestration and cloud environments (e.g. AWS).
• Experience with message queues / streaming (e.g. Kafka) and event‑driven architectures.
• Familiarity with A/B testing and experimentation platforms.
• Front‑end experience in design systems / component libraries and accessibility best practices.
• Previous experience in e‑commerce, travel, payments, or fraud/risk domains.
